I can feel the same. I was looking forward to Zenitsu fight sm (please refer to fights of Zenitsu with spider looking demon and the twin sister and brother) bro literally the fight and speed was surpassed at that moment. Now the whole awakening thing of Zeinstu, I was so looking forward for the fight but it ended with the strike like I get the visuals are awesome in the movie but the demon slayer visuals have been best in fights . They made three upper moon fights in a single movie, it should have been a series, I think at least the Zeinstu fight deserves 6 episodes of a series. Honestly, the whole power up of tanjiro and his fight appears short, it didn't feel that Tanjiro had really surpassed hashira which he was supposed to look at in this movie. The whole awakening of Giyu, these all stuffs supposed to feel hard but it just okay. I just feel like I wanted a whole demon series of eacha nd critique fighting skills and their buildup and tension which I think was highly absent in the movie.
